From the few people that have done the IPF it has been shown to give more HP gains than the trifecta. Most of the modded 6s have all agreed that tirfecta is a glorified way of taking off the CEL that comes with headers. Most people have said that there cars are running better without the tune.

when I originally got my Trifecta tune I felt the gains. but after I did more mods I went back to stock for an issue I had, and when I retuned I didn't feel it really. Now as far as how my car runs, it runs great with my tune, I don't feel like ive lost power, and my mileage if I don't use ghost cam isn't negatively affected.

I have yet to be "WOW'd" by any mods performance-wise. (My butt-dyno must be getting fat, old, and cynical...) I must say that the Trifecta transmission tune came the closest though. A close second is the Vararam - not for the performance - but for the change in sound at WOT. I haven't had any issues with the Trifecta tune, my car is running well; but I've read about people feeling that things got better for them after taking it off. I must admit I would like to get an wideband AFR gauge on the car because I've also read about a lean-running issue one member on here had with a Trifecta tune. But that may have been particular to his car/application.

As gustavson said, tran tune is the most noticeable. I have Injen longtube CAI, Ported throttle body when the tune was installed. Have added the ice-olater and need to get a data log back to them to see if it needs adjusting. Mostly I think it is tying all the mods together and making them play nice. Ipf does a great job also.
